How to configure t1 connection

techiie

Is there some video series that explains how to configure a t1 connection. I know in ccna studies explains how to configure serial lines and clock rates. Is there one that explains how to configure t1 like in the ccna voice or something else.

yeah the ccna voice would cover configuring CAS/CCS T1

INE CCNA Voice VoD

Thanks for the reply. What specific video has the configs. I don't want to have to watch the whole series for a ten minute explanation.

well if you want to get good with it I suggest watching the entire video. Setting up a PRI can be a little trickier than a traditional T1. The Provider should give you a list of what they have on there end as far is Line coding, Framing and clock rate. You also have to setup the ISDN switch type, and how many channels you plan on using for voice. Also we don't know the gear your using. I suspect you are in the US or Japan as they are the big T1 users. Below should give you a start.

Are you setting up a PRI?

Here's a pretty basic


controller T1 0/0/0
framing esf
linecode b8zs
cablelength long 0db
pri-group timeslots 1-24
!
controller T1 0/0/1
framing esf
linecode b8zs
cablelength long 0db
pri-group timeslots 1-24
!


interface Serial0/0/0:23
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice voice
no cdp enable

interface Serial0/0/1:23
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice voice
no cdp enable

wait so you can configure a T1 line? I though you just get it from an ISP and plug it to your CSU/DSU

You always need to configure a T1, even the CSU is configured to accept the T1.

When you take a T1 and plug it into a WIC on your router you're just bypassing the csu because it's integrated.

This in particular is setup for PRI
